At a Glance

What's working: You've developed a powerful workflow around multi-agent investigation for complex production bugs — spinning up parallel agents to trace interacting root causes across your Rails backend and TypeScript frontend, then synthesizing findings into committed fixes in a single session. Your full-stack debugging pipeline (production triage via Kamal → root cause analysis → fix → commit) is impressively efficient, and you've landed several ambitious multi-file migrations by breaking them into phases and iterating through issues rather than giving up.
What's hindering: On Claude's side, first implementations frequently come back with prop mismatches, wrong argument types, or framework-specific errors that require two-plus rounds of fixes — and Claude often starts in the wrong environment entirely (mobile instead of web, local commands instead of Kamal). On your side, some sessions get consumed by elaborate multi-agent planning and research phases that never reach implementation, and Claude doesn't always get the target context it needs upfront to avoid those false starts.

Big Wins

Multi-Agent Orchestration for Complex Investigations

You consistently leverage Claude's Task tool to spin up parallel agent teams for deep investigations — diagnosing interacting root causes across multiple files, auditing ActionCable streaming correctness, and researching pipeline issues simultaneously. This pattern lets you tackle systemic bugs (like the 3-root-cause incomplete-message bug) that would be extremely tedious to untangle sequentially, and your sessions show you're skilled at synthesizing the agents' findings into targeted, committed fixes.

Full-Stack Production Debugging Pipeline

You've built a remarkably effective workflow for diagnosing and fixing production issues end-to-end — from tracing a rate-limit error being swallowed as content, to identifying Kamal deployments killing workers mid-stream, to implementing graceful shutdown with PID tracking. You move fluidly between production investigation (via Kamal exec), root cause analysis across Rails backend and TypeScript frontend, and shipping committed fixes, often in a single session.

Large-Scale Migrations with Iterative Refinement

You've executed several ambitious multi-file migrations — React-to-Preact swaps, React-to-Svelte conversions, full route refactors, and 77-file doc audits — by breaking them into phased plans and driving them through to staging and production deployment. When issues surface (broken styling, stale caches, prop mismatches), you iterate quickly rather than abandoning the approach, consistently landing these large changes with successful builds and commits.
